Definitions

  • the present invention relates to a heating control installation capable of managing a large number of electric heating elements fully automatically under the best conditions of economy, security and flexibility of use.
  • the object of the invention is to provide a versatile installation capable, not only of performing the known load shedding functions in the event of exceeding the subscribed electric power and of regulating the basic heating and the auxiliary heating, but also capable to perform an optimization function, that is to say to obtain maximum comfort in the minimum amount of time with the minimum expenditure, to enslave all of these functions to the hourly conditions of pricing and detecting and reporting certain faults or anomalies.
  • the subject of the invention is a heating regulation installation comprising a certain number of electric heating elements supplied from an electrical energy distribution network and disseminated in a certain number of premises for professional use. or residential, characterized in that it comprises a computer assembly connected, on the one hand, by means of an appropriate terminal block, to a series of temperature probes arranged in determined locations inside and at outside said premises and, on the other hand, via an appropriate terminal block, to electrical contactors for selective connection between the current source electric and said heating elements distributed in the various heated zones, the computer being programmed to periodically and sequentially interrogate said probes and control, depending on the timers detected by the probes and various predetermined and / or preprogrammed parameters, selective activation or deactivation , via said contactors and for a determined time, the heating elements concerned.
  • Such a device makes it possible to ensure a certain number of regulation corrections as a function of the actual temperature variations in various places of the installation so that a real optimization of the regulation is obtained, that is to say the maximum comfort in the minimum time, with the minimum expenditure.
  • the installation shown in FIG. 1 comprises a low-voltage three-phase power supply symbolized at 1 connected to a power terminal block 2 itself connected to the various electric heating elements (not shown) constituting the assembly to be regulated.
  • connection between the power supply 1 and the different outputs of the terminal block 2 in the direction of the various heating elements is made by two series of contactors.
  • a first series C b of contactors (only one being represented in FIG. 1), are assigned to the so-called basic heating, each contactor C b ensuring the supply of electrical energy to a certain number of basic heating elements grouped in one determined area of all the premises to be heated (for example a contactor C b controls the basic heating of apartments on the same level or floor however that all the basic heating elements of all the common areas are controlled by a contactor C b ).
  • a second series C a of contactors (only one being represented in FIG. 1) are assigned to the auxiliary heating, each contactor C a ensuring the supply of electrical energy to the auxiliary heating elements of the same apartment, however contactor C extra control heating said common areas.
  • the different contactors C a , C b are selectively controlled from a computer 3.
  • the computer 3 receives information from thermometric probes 4 of which only two are shown in FIG. 1. These probes, in variable number depending on the size and configuration of the premises to be heated, are arranged one on the exterior facades of the buildings, for example at the four cardinal points, others are arranged in the common areas, others finally are each placed in one of the dwellings or premises to be regulated.
  • the probes 4 are connected to the computer 3 via an appropriate terminal block 5.
  • the computer 3 also receives information (technical alarms) from a terminal block 6 connected to the various alarm or technical signaling systems of the residential complex (elevator, fire, presence of water, television, break-in, mechanical ventilation controlled, etc ).
  • the assembly 8 supplies direct current to the computer 3.
  • the computer 3 is connected to an analog load-shedding ammeter 9 also connected to a general low-voltage switchboard symbolized at 10.
  • FIG. 2 shows in more detail the structure of the computer assembly and its peripheral connections.
  • the computer 3 has a known structure and comprises a central unit 12 associated with a coprocessor 13, with a random access memory 14 and its backup 15, to a program memory 16 of the EPROM type, and to a legal time clock 17 via a bus 18 for connection to the various interfaces.
  • the power terminal block 2 is connected to the bus 18 by a series of 1 to 14 cards 19 called power relays, with eight outputs per card and by a series of 1 to 7 cards 20 called power control cards.
  • the terminal block 5 of the probes is connected to the bus 18 by an analog multiplexing card 21 and an analog / digital conversion card 22.
  • Terminal block 6 for technical alarms is connected to bus 18 by a decoupler 23 and a card 24 with n all-or-nothing inputs.
  • the video screen 11 is connected to the bus 18 via an interface 28 (controller / screen cabinet).
  • a keyboard 29 with a keyboard interface 30 makes it possible to communicate with the computer.
  • a printer 31 with its interface 32 and magnetic recording units 33 with their appropriate interface 34.
  • the device performs the traditional load shedding functions if the subscribed power is exceeded, and basic heating, supplemented by an additional heating to reach the comfort temperature.
  • the computer 3 optimizes the regulation of the heating in the various parts of the installation according to actual data. supplied by the various temperature sensors 4 and according to the time bands.
  • the computer 3 sequentially interrogates the various probes 4 and possibly, depending on the local temperature values supplied by said probes, modifies the pre-recorded control program (at 16) of the installation heating.
  • This modification is made at the only places requiring an increase or a decrease in heat input by an action on the auxiliary contactor (s) A assigned to said places as well as possibly on the basic contactor (s) C b assigned to said places .
  • the excitation or de-excitation of these contactors C a , C b by the computer ensures the activation or deactivation of the heating elements concerned.
  • the duration of the local modifications made by the computer 3 is either predetermined (and variable depending on the zone of the installation concerned), or fixed from the data supplied by the probes concerned.
  • the calculator takes into account the time slots and, in particular to avoid consuming power as much as possible during peak hours, it will increase, depending on the outside temperature, for example one hour before the start of peak hours, heating provisionally so that during peak hours the heating can be switched off.
  • the heating can be restarted if the temperature in the apartments drops below 18 ° C.
  • the computer can also report anomalies. For example if during peak hours the temperature in a given apartment drops below 18 ° C, while this is not the case in neighboring apartments, the computer controls the auxiliary heating of said apartment and, if the temperature rise is not effective after a predetermined time, cuts the heating and signals an anomaly.
  • the computer also signals any anomaly detected by one of the technical alarms connected to terminal block 6.
  • circuits 25 to 27 ensure operation in automatic but not optimized mode, that is to say, the heating is controlled by the pre-recorded and memorized program, without keeping account for any variations in temperature detected by the probes 4.
